To access real-time 3D image computing environments, self-projection is very often achieved by means of a digital avatar controlled by a user. This project will question this duplication and this subjective teleportation across three disciplines: communication, engineering, and design. The idea is to seize the opportunities that have been opened up by avatars in terms of design, active education and body remediation in a retro-prospective manner, and in cognitive, creative and emotional terms.
